Belt tensioners - which do you recommend?

[Davegollick]

Good morning Folks
I'm having some vibration and whining noises which I'm told may be the belt. I've looked at Lamonster and Slingmods versions. Which one would you recommend for my 2020 F3S?

Smooth spyder
heavy duty, adjustable site sponsor.

I’ve got the lamonster. He’s a sponsor too and very happy with it.

I've had Lamonsters twice, once on my '18 RT and again on my current '21 RT. Highest quality. I chose Lamonsters version as it has a larger wheel and either a bigger bearing or 2 bearings. (Sorry. I can't remember which it is.)

I've had good luck with 2 different Jim's Smooth Spyder. One had about 25,000 miles on it and was doing good when I sold my 2013 RT. My current 2014 RTS has over 35,000 miles and still going strong!
